I have a registration page and I want to compare two passwords (input fields) to be equal before writing it to a websql database.
I cannot seem to get it to work.
Any ideas?

function addTodo() {

var todo = document.getElementById(todo);

  var todo2 = document.getElementById(todo2);



  if(todo != todo2) {

    alert(Yours passwords do not match);

  } else {

    curatio.webdb.addTodo(todo.value);

    todo.value = ;

    alert(Your Registration was successfull);

    setTimeout(function () {

    window.location.href = login.html; 

    }, 1000);

}

}





<div data-role=fieldcontain >

            <label for=todo>

                &nbsp;Password

            </label>

            <input name= id=todo placeholder= value= type=password required>

            </div>





            <div data-role=fieldcontain >

            <label for=todo2>

                &nbsp;Retype your Password

            </label>

            <input name= id=todo2 placeholder= value= type=password required>

            </div>
